This invention relates to churns and butterworkers. More particularly, the invention relates to the arrangement of elements for satisfactorily supporting churns and butterworkers of the sanitary type, having a horizontal, rotatable drum provided interiorly with fixed shelves and baflle means for the agitation, blending and working of the cream and butter.

In churns and butterworkers of the sanitary type when constructed of wood, distortion and warping of the wood may frequently occur. It is, therefore, essential that the construction be such as to prevent objectionable warping or that allowances be made for such possible distortion or warping of the drum and drum head or ends of the assembled churn drum to prevent the development of undue strains in the supporting and driving mechanism, which strains are normally brought on by such distortion or warping. It is also desirable in the construction of sanitary wooden churns and butterworkers to avoid as much as possible the use of exposed meta1 parts, packing glands or other similar elements on the interior of the churn, which elements may present unsanitary surfaces and which, if not meticulously cleaned, constitute sources of contamination of the product manufactured in such churnsand butterworkers.

The accompanying drawings illustrate theas'i pects of theimproved design in a support arranaement for a churn and butterworker which is a simple and inexpensive construction as contemplated by this invention. However, the invention is not to be limited to the specificembodiment disclosed. The features of the improved churn and butterworker illustrated in the accompanying drawings, which features relate particularly to the novel shelves or baffles and to the particular arrangement thereof within the (humor the churn and butterworker, are'described and claimed mor specifically in my co-pending. ap-j plication Serial No. 249,056, now Patent 2,359,744

The particular object of this invention is to provide an improved churn and butterworker. comprising a. cylindrical, horizontally disposed, rotatable churn and butterworker. drum. having a plurality of longitudinally extending, fixedly mounted shelves within the drum intermediate the end walls or heads of the drum.

A further object of this invention is to provide an improved arrangement of elements for supporting the drum of the churn and butterworker in such a manner as to accommodate expansion, contraction, distortion or warping of the drum of the churn and butterworker without producing or applying substantial stresses or strains in the sup-,

parts within the interior of the drum of thechurn and butterworker is avoided.

Other important features of this invention will be more apparent uponthe examination or the details of the construction of the improved churn andbutterworker, including the alternative arrangements or construction for supportingthe shelves or baflles within the drum of the churn and butterworkenin which arrangement these:

To thus support the assembled drum l I. drum heads [2 and I3, as well as the interior shelves, there are provided bracket blocks 1 each of which block-s is internallyprovidedw ithsuitable bolt anchorage, such as a metal rod I8, having several drilled or tapped openings IS. The rod 18 in each instance is sealed into the longitudinally extending opening 26 of the associated *blockl-l by stoppers 2i, all as clearly illustrated in Figures v6 and 8.

In the embodiment of the invention as illustrated in Figures -1 to 8,-incl-usive, there is shown a supporting arrangement for the drum of the churn and butterworker similar to the =arrangement disclosed in the United States Patents No. 1,- 805,46l and No. 1,805,753. ;:In--general, the trunnions cooperating with the supporting spiders or gudgeons are mounted in any conventional type of {journal in astandard, in which the journal is provided with endthrust features and in which the bear ings are carried at the upper portion-pf the standards, such as the standards 30 and 33. As illustrated, the trunnion, coacting with the sup porting spider or gudgeon fixed to the end wall 12', is carried by a suitable drive unit hired to the standardf33, which driveunit is generally in dicated' by ithe numeral 32.

.I;n ,fi-Xlng the supporting spiders orgg-udgeons to the end :walls or drum :heads. l2 andll 3 of the drum H, as above described, itis to be..-obsenved that thezuse o'ffexpos'ed"metal parts on th'e in: terior of the churn' 'drum has beementneiy avoided and that the resulting structure, censisting of the gudgecns 'or spiders, drum neads and shelves,:inae endentlyrcrmsa rigm iinitary structural assemble'ge. Such" a construction isdesirable in that it prevents theobiectionable exposure ofmetal parts on the interior of the drum of the churn and butterworker and further provides various advantageous structural or operative features. The presence of exposed metal parts within the drum of a wooden churn and butterworker, particularly when such metal parts are in contact with the wood, tends to cause deterioration of the wood, as well as the metal, which deterioration when present may have a detrimental effect on the quality of the product or. products produced in a churn and butterworker. It is, of course, needless to indicate that the interior of the drum of the im-. proved churn and butterworker, as illustrated in the drawings, may be readily and easily cleaned and the deterioration of the drum heads and shelves of the improved type of churn prevented when the elements used in the aforedescribed supporting arrangement do not include the use of exposed metal parts on the interior of the churn. The present type of structural arrangement, as just described, accomplishes this objective, as well as providing a very rigid drum, drum head and shelf arrangement, in which the drum heads and shelves are compressed between the opposed gudgeons.

The invention contemplates the use of shelves or baiiles for the agitation, working and blending of the cream and butter being processed within the improved churn and butterworker. The improved shelves and the arrangement thereof are clearly set forth in the co-pending application, Serial No. 249,056, of which this is a division.

As shown in Figures 2, 3 and 4 of the drawings, the drum of the improved churn and butterworker is provided with a plurality of closed face or imperforate agitation shelves or bailies 34, 35 and 35, the ends of which are supported on brackets I! on the inner face of the drum heads or end walls l2 and I3 of the drum H. The shelves or baflies are braced intermediate their ends by braces 31 fixed to the interior of the longitudinal wall of the drum II. The shelves 34, 35 and 36 are spaced slightly from the inner periphery of the drum ll but are supported upon the brackets I1 and braced by the brace 31. The rear edge of each of the shelves 34, 35 and 35 is parallel to the adjacent wall of the drum II. The shelves 34, 35 and 35 are not radially disposed with respect to the longitudinal axis of the drum H but instead the shelves 34 and 35 are angularly arranged with respect to the radii of the drum i l. The shelf 36, which is the unloading shelf is also angularly disposed in a manner similar to the shelves 34 and 35. The rear edges of all of the shelves are equally spaced relative to the inner surface of the drum II and are spaced equally from one another.

The improved churn and butterworker is provided with a splitting bar or central baflle member 38 supported substantially centrally within the drum I l. The bar 38 is preferably of circular cross-section and extends along the longitudinal axis of the drum. The bar 38 is rigidly fixed at each end to the adjacent drum head or end wall l2 or l3 by a bolt 35 which passes through the adjacent end wall and is anchored to the metal cross bar 40 imbedded in the adjacent end of the bafiie or splitting bar element 38. The crossbar 4B is sealed in the end of the bar 38 by stoppers 4|, as clearly shown in Figure 5 of the drawings. The splitting bar or baifie 38 is positioned in the churn drum in such relation to the shelves 34, 35 and 36, so as to cooperate with them in the 6 working, blending and agitation of the cream and butter being processed.

For determining the progress of the churning operation, inspection windows or indicators 54 are provided at either-end of the drum 1 I. When the working operation of the butter is completed, it is, of course, desirable and necessary to accumulate the same on the wide or unloading shelf immediately ahead of the churn door. When the working operation is completed, the churn is stopped with the door 42 in the unloading position, as, illustrated generally in Figure 1 of the drawings, and the churn is locked in this position by a swiveled pawl 43 mounted on the tubular frame element 3| by the clamp 44. The locking is accomplished by engaging pawl 43 with the rack 45 mounted on the adjacent end of the drum II by bolts 46. To facilitate emptying the drum H there is provided a conventional type of discharge outlet '55 mounted in one of the end walls or drum heads l2 or l3 of the drum H adjacent the outer periphery thereof.

An important feature of the invention relates to the manner of supporting the ends: of the shelves or baiiles in the churn barrel, whereby the shelves are removable and rigidly supported without the use of any exposed metal parts. The shelf supporting arrangement shown in Figures 6 and 8 involve the use of the bracket H at each end of the shelf. The bracket i1 is partially fitted into a corresponding recess 22 in the end wall I 2 or l3 of the drum II. The bracket IT is held rigidly in place by the gudgeon anchor bolts 29, which are fixed to the anchor bar Hi. The shelves resting upon the brackets I! are fixed thereto by the countersunk bolts 41 extending through the shelves into the brackets l1 and suitably threaded into the bolt anchorage I8housed within an opening in each of the brackets I1. Stoppers 48 are fitted into the countersunk openings of the shelves to seal therein what would otherwise be an exposed metal surface of the bolts 41.

An alternate construction for the supporting of the shelves in the churn barrel is shown in Figure 7 of the drawings. In the alternate construction shown in Figure 7, each of the brackets i1 is replaced by an end of one of the shelves 34, 35 or 36. By fitting such replacing end of a shelf, as, forexample, shelf 34, tightly into the recess 16 .the likelihood of splitting the end of such a shelf by tightening the associated bolts 29, which tightening applies pressure to the bolt anchorage l8 provided in an inner opening in such end of the shelf, is substantially avoided. In this alternative construction, it is, of course, not necessary to separately fix each end of the shelf to its associated bolt anchorage [8 as is necessary in the preferred type of construction which is illustrated in Figure 6 of the drawings. I

Mounting the various shelves of the improved churn and butterworker upon the brackets H, to whichthe churn supporting spider or gudgeon terminals 21 are fixed, provides an extremely satisfactory andeconomical arrangement for supporting the drum, drumheads and shelves of a churn and butterworker. As is clearly illustrated in Figure 3 of the drawings, the anchor bolts 29, which secure the spider terminals 21 to the bracket blocks H, are not arranged in parallel alignment with the grain of the woodof the end walls or cylinder heads I 2 and I3. This is obvious upon an examination of the arrangement of the bracket l'1 into which the anchor bolts 29 extend after passing through the drum heads or cylinder H or l3; By avoiding: suchparallelz ment, the possibility of splitting the end walls or cylinder heads l2: and 13 due to impact strain caused by the droppingoi' cream or butter upon the. shelves or bafiies during :thechurning opera-. tion isi'substantially minimized. V

The improved. arrangement for use in a V churn and butterworker, as herein described," prov-ides: a. very simple and efficient construction for the rigid support of the shelves or baffle-s, drum head and cylinder of achurn and butterworken There are no relatively movable parts within the improved churn and butterworker and exposed metal parts within the interior of the churnbarrel, common ina conventional type of churn, have beenentirely avoided. The novel manner of mounting the drum heads and shelves of the churn and butterworker directly upon the supporting" spiders or gudgeons by securing the terminal ends or pads at the ends of the arms of the-supporting spiders or gudgeons to brackets associated with the drum heads, which brackets also support the shelves in the interior of the'drum, or the fixing of such terminal pads directly to the ends of the shelves is a decided improvement over the support arrangement used in the conventional type of churn. The improved arrangement for supporting the drumheads and shelves directly upon the gudgeons or spiders also provides a structural design in which the rigid, well-braced, interlocked construction is secured between'th-e supporting gud'geons, the drum heads and the churn shelves or baiiies entirely independent of the drum or' It will, of course, be understood that various detail alterations and arrangements of the principal elements which have been described and which have been illustrated in the accompanying drawings may be made by those skilled in the art within the scope of the invention asset forth in the appended claims.
